HERMAN G. LOEFFLER, OF BAY CITY, MICHIGAN.

POTATO-PEELING KNIFE.

SPECIFICATION forming part of Letters Patent N 0. 577,384, dated February 16, 1897.

Application filed March 9, 1896.

To all whom it may concern.-

Be it known that I, HERMAN G. LOEFFLER, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in a Potato-Peeling Knife; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in a potato-peeling knife; and it consists in the arrangement and construction of the parts, with the object of producing a device for peeling potatoes, with the peeling-knife so arranged as to cut a thin peeling when passing over the rough surface of a potato, with the object of avoiding cutting a thick or heavy peeling, so arranged that the peeling-knife may be removed from its working position for the purpose of renewing the sharpness on its cutting edge and conveniently and easily replaced to its position, and at the same time produce a simple and cheap device in its design and manufacture.

The invention consists in the novel arrangement and construction of'the parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be'had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all of the illustrations. Figure 1 represents a front elevation of the potato-peeling knife. Fig; 2 represents aside view of Fig. 1. Fig. 3 is a side view of a supporting-stem, showing its blank form when prepared from a bar of metal. Fig. 4 is a peeling-knife. Fig. 5 is a top plan view of a ferrule that supports the lower end of the peeling-knife. Fig. 6 is a side view of Fig. 5.

A represents the stem of the device, and B is the handle, which is provided with square openings. (Shown by dotted lines at O.)

I is a nut, and O is a ferrule which is provided with a j ournal-bearing D, an upwardlyextending pin E, and a rectangular openingF.

G is the peeling-knife, which is provided with journals H H.

The stem A has a knife-blade J provided on its upper end for the purpose of cutting out defective parts which often occur in potatoes.

Serial No. 582,414. (No model.)

The lower end or stem M, that supports the handle, is made square for the purpose of preventing the handle B from turning thereon, and the shoulder N forms a stop for the same. The lower or inner end of the knife-blade J has a lug K formed thereon which is provided with a perforated hole L, which is bent at right angles with the said blade J and forms a journal-bearing thereby, as shown in Figs. 1 and 2. The ferrule G is placed on the upper end of the handle B and secured thereon. The upper journal H of the peeling-knife G is inserted intothe perforated opening L of the lug K. The square end of the stem-support M is inserted into the square opening F of the ferrule O and through the opening 0 of the handle B, up and against the shoulder N, with the lower journal H of the said peelingknife G inserted into the perforated opening D and journaled thereby. The handle is then secured in its position by means of the nut I, screwed on the lower end of the handle-stem M, which draws the said handle B and ferrule C firmly together and up against the shoulder N.

The peeling-knife G is adjusted to the required thickness of the peeling by the location of the pin E, which is driven into the upper end of the ferrule G and down into the upper end of the handle B to a suitable distance to hold it firmly in position, whereby the back of the peeling-knife G drops back against the pin E to a suitable angle or degree and is supported thereby, and at the same time the said peeling-knife G is placed on the proper angle or degree to cut a thin peeling by the stem A resting upon the potato,whereby the peeling-knife Gis prevented from cutting into the potato a distance beyond the thickness between the cutting edge of the said peeling-knife G and the stem A.

In removing the'peeling-knife Gfor sharpening or other purposes it is only necessary 'to remove the nut I from the lower end of the stem M, then by sliding the handle downward releases the lower journal H of the said peeling-knife G, whereby the said journal H may be slid out of its position and sharpened or other desired repairs executed and at the same time producing a device that is simple and cheap in its design and manufacture.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. I11 combination with the handle of a peeling-knife the main blade thereof provided with a flange in which a bearing L is formed, a stem having a shoulder N, and a long shank M screw-threaded at its end a handle B having a central opening through which the said shank passes, and a bearing D fixed thereto a nut turning on the said shank, and a peeling-blade G journaled in said bearings so as to be clamped in place or set free by the action of the said nut substantially as set forth.

2. A ferrule provided with a bearing" and a gage-pin in combination with a blade having a flange turned and perforated to form another hearing, a peeling-blade reinovaloly journaled in the said bearings, a handle on which the said ferrule is fitted, means for drawing the said bearings toward each other or moving them away from each other at will substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HERMAN G. LOEFFLER.
